I'm trying to compile a list of free recruiting stuff. Any suggestions?

Does anyone know of any other products or services that are available to recruiters to use free of charge? I'm trying to compile a list on a website so recruiters can access all the free stuff out there in 1 place.

If you're looking for a place to post your jobs and brand your company check out ultimatejobboard.com

Brief writeup:

Founded by Christopher Poreda, a former President and CEO of an executive search firm, ultimatejobboard.com was developed on the principles of intuitive user experience, a clean and elegant design and superior search capabilities by combining the latest developments in technology and social media tools. UJB has taken a proven, highly effective existing model and added superior search capabilities and meaningful social network integration, while destructing and redefining the business model. It’s free to search and free to post; post as many jobs as you like and keep them posted until they’re filled. Purchase a Premier Partnership and job postings are highlighted at the top of search results receiving over 17 million unique views per month. Plus, we’re the only job board to offer incentives like no contracts, a price for life and money back guarantee for an unlimited number of premier job postings at a monthly rate less than a single job posting on other popular sites.

Poreda insists that, “Although easy to use, the technology is complex and cutting edge. Our team worked diligently developing the site to ensure the best possible user experience. Our mission is to create a platform where all job seekers and those who wish to engage them have access to each other, regardless of budgets and other familiar constraints. Now, I recognize the concept of free is not a new one, but free should not be at the expense of the user and each user should have the option to pay for additional services for additional exposure."
